constant circulation of wateras maintained.

while the heating-receptacles are subjected to the heat of the sun.

Heretofore in solar heaters the heating and storing of the heated waterhas been in the saine receptacle, whereby only a limited arnount'ofwater could be heated at a time, because the heated water along the toof the receptacle would prevent the full uti `zation of the suns rays,and the water at the top of the receptacle would be unduly heated, be'

cause always vsubjected to the'heat from the suns rays, while the waterin the lower portion of the receptacle would not be sufliciently heated,because of the imperfect circulation of the water in such' structuresand the absorption of the heat b the up er stratum. of water. I obviatet is difficu t and obtain a perfect circulation and the full utilizationof the heat of the suns rays by the device described herein andillustrated in the accompanying drawings, in which- Figure 1 is aplan'of a solar heater .embodying my invention equipped with three Fig.2 is a section on the line 2 2 of Fig. 1 and a section of acorner of aroom with the storage-reservoir therein in centralsection. Fig. 3 is anenlarged central section through one of the heating-recep In' thedrawings, 5 is the usual Wooden case, which is vprovided with atransparent top 6. Hthin the case is a reector 7 for directing back uponthe under side of the heater such rays as rniss the heater in thedownward passage of the rays. Located within ythe case and above thereflector are a plurality of heatingweceptacles 8, which-are preferablyformed of thin sheet nietahwith the walls cone-shaped, as best shown inFigs. The wallshof the receptacle are tense heat as it enters thereceptacle.

quite close together, and the apex of the cone is placed downward, oraway from the sun. A connection is made at the apex of the receptaclewith the supply-pipe 9 by means of a branch pi e 10, which connects thesupplypipe to the eating-receptacle when there are a plurality ofheating-receptacles within the glass-covered case. These branch pipesare preferably smaller than the main sup lypipe. used, the supply-pi ewould be connected directly to the apex t ereo. In the outer wall,preferably at a oint farthest removed trom the apex thereoi), the metalis preferably expanded to form a channel 11, and to this channel thedelive T-pi e 12 is connected. Where there are a I 12 are connected to a'common delivery-pipe 13, which leads to' and o ens into the upperortion of the storage I{Jnoiler or tank 14.

upply-pipe 9 is connected to and opens into the lower portion of thestorage-tank 14. This storagetank is provided with the ordi* narysupply-pipe 15, which is connected to a source of watersupply- (Notshown.) Storage-tank 14 is also' provided with the usual When a singleheating-receptac e is ura ity'gof heaters, pipes serviceipe 16, whichleads to the place' of use. T e glass-covered. case containing theheating-receptacles is preferably placed .on the sunny si e of the houseat a point below the bottom of the storage-tank. By this construction itwill be seen that as the water is heated' in the receptacles it 'willrise and pass into the storage-tank and the colder water from thestorage-tank will -pass -into the fis heater than when used without suchaglass,

as the water is thereby subjected to 'any burnin -glass is held in frame18, which vis prefera ly supported bylegs 19, which are secured to thestrengthening-ribs 20whicli` ribs are secured to the upper walls of therece tacle to strengthenthe same.
